Lambrecht (Lambert) Duppijns of Haarlem, an Anabaptist martyr, was beheaded on 2 June 1539 at Haarlem, in the Dutch province of North Holland. Duppijns was arrested in his own house on 23 May with his wife and a few other Anabaptists. When the house was searched about 500 copies of unbound books by David Joris were found and confiscated. On 24 May Duppijns was tried; he refused to admit the stay of David Joris at his house. Thereupon the officials took recourse to a trick. Adriaen Adriaensz, an Anabaptist who had recanted, was imprisoned with Duppijns, pretending to Duppijns that he was still a loyal member. So the officials learned the secret. On 28 May Duppijns was tortured a second time. Duppijns, who was a native of the bishopric of Münster, Westphalia, Germany, was a David-Jorist, as were his wife and the whole company meeting in his house.
